what question did you want answered about these codes?

Car don't even accelerates
Expert:  Steve replied 2 years ago.
I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
This is most likely due to a failed throttle body or failed throttle body wiring harness. The harness needs to be checked and if nothing is found, the throttle replaced.
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
